    Iodine deficiency can lead to the enlargement of the thyroid gland, a condition known as goiter. The thyroid gland requires iodine to produce thyroid hormones, which are essential for regulating metabolism. When there’s insufficient iodine intake, the thyroid gland enlarges in an attempt to capture more iodine from the bloodstream, resulting in the formation of a goiter. Thyroid hyperactivity (a) is associated with conditions like hyperthyroidism, and midgetism (c) is a term used in the past for a form of dwarfism, which is unrelated to iodine deficiency.

  2. Heart attacks are primarily caused by (c) Lack of blood supply to the heart. This occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked, often due to the buildup of plaque. This deprives the heart muscle of oxygen and nutrients, leading to tissue damage aRead more

    Heart attacks are primarily caused by (c) Lack of blood supply to the heart. This occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked, often due to the buildup of plaque. This deprives the heart muscle of oxygen and nutrients, leading to tissue damage and potentially a heart attack.

    Heart attacks, medically known as myocardial infarctions, are typically triggered by the sudden rupture of a plaque within the coronary artery, leading to the formation of a blood clot that obstructs blood flow. This interruption of blood supply causes damage or death to part of the heart muscle, resulting in a heart attack.

  3. Carbohydrates are stored in plants and animals primarily in the form of (b) Starch and Glycogen. Starch serves as the main storage carbohydrate in plants, found in structures such as roots, tubers, and seeds. Glycogen, on the other hand, is the main storage carbohydrate in animals, stored primarilyRead more

    Carbohydrates are stored in plants and animals primarily in the form of (b) Starch and Glycogen. Starch serves as the main storage carbohydrate in plants, found in structures such as roots, tubers, and seeds. Glycogen, on the other hand, is the main storage carbohydrate in animals, stored primarily in the liver and muscles. While glucose is a simple sugar and a component of both starch and glycogen, cellulose is a structural carbohydrate found in plant cell walls and is not used for energy storage in either plants or animals.

  4. The white color of milk primarily arises from the scattering of light by various components within it. While milk contains several compounds, the main contributor to its white appearance is (c) Carotene.

    The white color of milk primarily arises from the scattering of light by various components within it. While milk contains several compounds, the main contributor to its white appearance is (c) Carotene. Carotene is a pigment found in the fat globules of milk, contributing to its slightly yellowish-white color. However, the concentration of carotene in milk is relatively low compared to other sources, such as carrots.

    Multi drug therapy (MDT) is for the infection of Leprosy. MDT involves the simultaneous use of multiple antibiotics to treat leprosy effectively. This approach targets different strains of the bacterium Mycobacterium leprae, reducing the risk of drug resistance development. MDT typically includes drugs such as dapsone, rifampicin, and clofazimine, administered over several months to years depending on the severity of the infection. By using a combination of antibiotics, MDT helps to improve treatment outcomes, reduce the duration of therapy, prevent relapse, and minimize the spread of leprosy in affected populations.
